I did not stay or see either of their two locations, but Infanticide brought these up as options in my Montreal report, and I had seen discussion of Le Chablis on MERB.

Although not mentioned on their website, Le Chablis offers a 4 hour rate, making these hotels viable outcall options for residents and visitors who do not need rooms for the entire night.

Le Chablis has two locations, Le Chablis St-Jacques and Le Chablis Cadillac. The Cadillac location is better for those using the metro with the hotel only .3km from the Cadillac stop. St-Jacques is 3.6km from the nearest stop, Vendome.

If you need rooms you'll be staying the night in, you're probably better off downtown for both convenience and pricing. The daily rates for St-Jacques and Cadillac start at $400CAN and $300CAN, respectively.

I'll probably stay at a hostel again on my next visit to Montreal, but I plan on using the Cadillac location for at least one outcall.
